" ATTORNEYS THE NORRIS PETERS CO., PHOTO-LITHOV. WASHINGTON, D- C- To all whom tt mdy concern 1 Be it known that I, OSCAR [Linn MCKIN- .LEY, ,a 'citizen rof the United States and a "resident of Demopolis in the county of Marengo and State of Alabama, have invented an Improvement Harrows, of which the following :is azspecification.

- My present invention relates to 'harrows and more particularly to sectional harrows, my object :bein'g'to provide a sectional hare or fronts or rears.

" u A'further object of; my 'inventionjis to provide a harrow sectionso formed' asflto permit of the arrangementfiof the harrow "teeth in atriangle of which'the'head tooth will be.direct1y:in line with the center the draft.

These and the other objects of my inven-, tion will beclearly apparent from the fol-3 lowing description in which reference is submitted to the accompanying drawings j' formingrpart of ithespecificationgand in which, R i I]. 511 A.

Fig. 2 is a side elevation thereofq zFigQ '3 5 is a .stran'sverse verticalgsectionon an enlarged scale, takenthrough one 5 side bar of one ,of the sections. Fig. isfa planview of one'of the sections,'its front andrear portions being broken away. Fig. 5 is a vieW similar to Fig. 3 illustrating a slightly i modified form of the frame bar. Figufi islaiv similar view; illustrating another modified formof frame ban -Fig.1 is ,a'jsimilar. yiew illustrating still another modified form;and"Fig.F8 isan the frame bar seen in Fig. 3. I

Referring now to, these figures, I i have shown in Fig. 1, a harrow made-up ofthree sections, eachof which is indicated at A and one of which 'is'shown in detail in Fig. 4. From this latter figure it'is to be noted that each of the harrow sections consists of a frame generally V-shaped in form and opening rearwardly, being provided at ltS apex with an elongated goose neck curve a and having angular extensions a at its ends arranged parallel with the line of draft. It will also be noted that the frame is con structed of a channel bar, the web of which is upright and theffianges of which are inturned.

"Pate curve a with an opening a and is also provided with openings a in the angular elong tionsfa at the {rear end "of the'frame. In this manner two sections .may :be coupled -injuxtaposed I relation by placing their' adjacent elongated ends a againstone" another and coupling these ends bymeans-of a con -necting bolt indicated in dotted lines at A 1111 Fig. .1. ELikeWisea third sectionmaybe I conveniently coupled'in front by means of split bolts qA having their rear ends connected through a the forward opening a of the rear sections and having their forward .tensions d;of' thefront section and secured y'byffastening members extending through .Ethe apertures a? :of said extensions; -In this 1 manner itywill be seen that a harrow may .be; formed bya plurality of sections assembledpwith'out regardto rightsJor leftsv-or Sea -4 frame is formed provided the extreme 5' forward central *portionof the goose: neck bifurcatedends straddling the elongated exfronts. 0r rears asbefore 'statedi' Each of lthe sections .A has a cr'oss brace 13 extend ing transversely thereof/adjacent its :rear (end and; a central: longitudinal brace B:the f1 -rear;end of which is connected intermediate the ends of the cross. brace, In this'manner .eachiofq the sections is, well! adapted I to the connection of a handle C, and itsbraces G From the structure of;the framethus;de- 1 scribed it will be readilyfsejen that 'the particular' structureof the'barfrom which, the arms is formed may be" .varied to a con- :siderablei-.extent. 'uT-his will beibetterrappreciated from a comparison of thesevera'l fi ures illustrating in detail difi'erent forms 0 bars. Thus'in Figs l to 'lsinclusive I l have" illustrated channel beam; 7 the er and'f'lower flanges of, which are of equal Iwidth. In Fig. '5 I haveshown the same structure varied slightly in so far as the width of the flanges is concerned, the lower flange d of the beam D in this figure being In Fig. '6 I have shown a half-roundbar E and in Fig. 7 is illustrated an angular bar F. In each of these forms the bar. is provided with an intermediate longitudinal 10(1 considerable wider than the upper flange. i

slot, such as shownat g in Fig. 8 in order to receive a clamping bolt Gr for clamping each of the harrow teeth H; the bolt being adjustable in slot gin order tohold its respective tooth either in a vertical position as shown'in full lineslin this figure or in in;

clined position as indicated in dotted lines. a

In the form shown in Figs. 1 tojf and 8 a the inner edges of the channel bar flanges are provided with notches in which the" harrow teeth are set in both their vertical and inclined positions, as is also the halfround bar as shown in Fig. 6. The angular bar as shown in Fig. 7 and the form" of channel bar as shown in Fig. 5 are'provided with openings in their lower flanges through .which the harrow teeth extend, the last mentioned form having notches in its upper flanges. As will be seen by referring to Figs. 1, 2

and 4 the harrow teeth H are distributed at equidistantlyspaced points along the inner surfaces of the frame sides, on tooth being located within the goose neckcurve a,

by virtue of which it is disposed centrally of. the line of draft and forms a true trianglev with the several other teeth in order to eliminate all side draft.

Referring now to Figs. 1 and 2it will also be seen that each of the sections is provided with an opening (1* intermediate each side thereof so that each section is adapted to receive the rear lower ends of an'upwardlya and forwardly inolined'draft connecting} I, secured thereto means of member bolts 5.

provide a harrow section from which a harrow'of suitable proportions may be readily and conveniently formed by assemblingqa selected number of sections without respect to rights or lefts, fronts or rears, and that I accomplish this important advantage by such means as will enableme to eliminate all side vdraftand permit of the formation of each section by means of bars of various types. It is to be understood of course, that although I have described theflan'ges of the 1 frame bars as extending inwardly in each instance, they maybe turned outwardly with equal facility and secure equal effectiveness In use. i I

It will thus be seen that I am enabled to "mam 1. A harrow, consisting of a plurality of rearwardly opening V-shaped sections, each "Qf'WhlCh sections is provided at its apex sections and passing through the openings of said extensions, .andwa. bolt secured through the opening of the goose neck curve of each rear section and connected: at its forward end to one of the rear extensions of one of the said sections, substantially shown and described. t Y

"2. A harrow section consisting of a sub--' 'stantially vrshaped frame having a forwardly elongated goose neck curve substantially in the :center of the. line of draft and having angular rearward extensions at its rear ends arranged parallel with the line of draft, the frame being also provided with aperturesiin the central forward portion of its goose neckcurive and through its rear extensions, andlia plurality .ofteeth adjustably connected along the frame sides, substantially as described. 1 i

1 .A'harr'ow sect-ion consisting of a substantially V-shaped frame having transverse and longitudinal braceyzmembers and having a forwardlyelongated goose neck curve-at its apex, and a plurality of harrow teeth adjustably mounted along the inner surface ofthe-frame, the forward tooth of which is disposed within the goose-Iieokcurve and in line with theteeth along that; ofthe frame 7 sideswhereby toxeliminate all side draft. 1 CARLE M IN Y,
